Assessment of table grape progenies and correlation between seedlessness and other agronomic traits

Abstract The aim of the present study was to identify grape parent varieties that lead greater frequency seedless genotypes in progenies and understand relationships between trait other fruit traits. A group 200 hybrids (F1) originating from 38 crosses among cultivars Vitis vinifera L. interspecific were evaluated Juazeiro, Bahia, Brazil, over six consecutive crop seasons (2018 2021). placed three classes based on seedlessness: completely (class 1), seed traces or soft seeds 2), with 3). mean dry matter each class 0 mg, 2.3 25.7 mg respectively, which corresponded 40 (20%) 1, 52 (26%) 2, 108 (54%) 3. cross ‘BRS Isis’ ‘Marroo Seedless’ stood out through favoring high individuals progeny (47.5%). traits associated berry size (length, diameter, weight) had positive correlations other. results obtained make an important contribution for table breeding aiming at development new cultivars.
